I have always wanted to try horseradish sauce and was wondering if someone could describe the taste?

It is a lot like a spicy mayonnaise. It is not a capsaicin spice like chile; it tends to hit the back of your tongue. If you have had wasabi you will understand the horseradish taste. It works really well on roast beef and ham; the base of the dish need to be able to hold up to a strong taste.
